Step Trimmer

Introduction

Before starting this guide, you should be able to follow the instructions without any prior knowledge with electronics. However, if you do not have experience with any wiring, follow these steps exactly. The device should be off and there is little chance of any electricity going through the system, but be sure to take all the precautions set out in this guide. While not necessary, you may use a pair of thin gloves while replacing this guide, however using the gloves will make replacing the battery slightly harder.

Take the new battery, place the red wire into the hole on the left that the original battery wire was connected. Heat up the solder already there and place the end of the wire directly onto the solder.

If you let go of the wire and it disconnects from the motherboard, then you may need to add solder onto the motherboard over the hole you put the wire in. Heat the end of the solder and place it over the wire as you add it into the correct hole (on the left in the picture shown).
